Dog Tick

During a 2-year study on the relationships between immature Dermacentor variabilis and their small-mammal hosts near Birds Hill, Manitoba, 739 captures of 427 mammals were examined for ticks. Captures represented 11 mammal species: Clethrionomys gapperi, Lepus americanus, Microtus pennsylvanicus, Mus musculus, Peromyscus maniculatus, Sorex cinereus, Spermophilus franklinii, Spermophilus tridecemlineatus, Tamias striatus, Tamiasciurus hudsonicus, and Zapus hudsonius. Clethrionomys gapperi, M. pennsylvanicus, P. maniculatus, S. franklinii, and Z. hudsonius were most frequently encountered and, with the exception of S. franklinii, infested with larvae and nymphs. Clethrionomys gapperi were most frequently infested by D. variabilis and produced 42.6% and 60.5% of larvae collected in 1979 and 1980, respectively, and over 85% of all nymphs. Peak larval infestation occurred between the last week of May and the middle of June; that for nymphs occurred in July in both 1979 and 1980. Dermacentor variabilis appeared to have a 2-year life cycle in Manitoba. Larvae were spatially aggregated during both years and aggregates were located in different areas of the plots each year. Nymphs were less aggregated than larvae. The distribution of nymphs overlapped that of larvae each year and occupied a greater area on the plots.

New Host Records

During the period March 1976 to November 1977, 377 mammals of the family Sciuridae (Rodentia) were collected in Saskatchewan and examined for helminths. Species and numbers of each were as follows: Spermophilus richardsonii (Sabine), 209; Spermophilus franklinii (Sabine), 46; Spermophilus tridecemlineatus (Mitchill), 31; Tamiasciurus hudsonicus (A. H. Howell), 64; Glaucomys sabrinus (Shaw), 12; Eutamias minimus (J. A. Allen), 11; and Marmota monax (Erxleben), 4.Ten species of cestodes, 2 species of trematodes, 11 species of nematodes, and 1 acanthocephalan were represented in the collections made. New host records and (or) geographic range extensions were indicated for 10 species of helminths.In addition to taxonomic considerations of the helminths, attention has been given to parasite–host relationships involving ground squirrels. In general, male Spermophilus spp. were significantly more commonly infected than were females, and older squirrels were significantly more commonly infected than were younger ones. However, adult squirrels did not have significantly more worms than did juveniles.

Dispersal Events

To better inform conservation and management strategies directed at Franklin’s ground squirrel, Spermophilus franklinii, I reviewed published and unpublished accounts of the squirrel’s distribution, abundance, and principally, habitat associations. I present the body of literature on S. franklinii and include portions of original accounts to avoid potential bias from paraphrasing. A consensus of the literature indicates that S. franklinii is most frequently associated with habitat characterized by a mixture of grassy and woody vegetation, referred to as savanna-like or parkland habitat. Moreover, S. franklinii has had an affinity for this type of habitat throughout its geographic range in recent, historic, and even prehistoric times. This is in contrast to a view of the species as primarily associated with tallgrass prairie habitat. As indicated in the literature, populations of S. franklinii are subject to marked fluctuations, which probably are influenced by local disturbances in addition to regular dispersal events. In the southern part of its geographic range, S. franklinii is currently limited in its occurrence principally to roadside and railroad right-of-ways. In these southern regions S. franklinii is justifiably of conservation concern. I suggest that more detailed surveys for the species (such as those that have recently occurred in Illinois and Missouri) take place in Iowa and Kansas.
